AN12185: A71CH Host Software Porting Guidelines
Detailed guide for porting the NXP A71CH Host Library to various platforms for secure communication with the A71CH security IC via I2C.
Overview
This application note provides comprehensive instructions for porting the NXP A71CH Host Library to different host platforms. It outlines the library architecture and identifies specific files requiring modification, such as I2C platform drivers, system timers, and print functions. The guide details the requirements for the SCI2C protocol, specifically the need for SMBus Block Read and Repeated Start support. It includes implementation examples for Linux environments using i.MX6UltraLite and RTOS or bare-metal environments using Kinetis K64F microcontrollers.
Use Cases
- Integrating the A71CH secure element into custom microcontroller or microprocessor platforms.
- Implementing secure cloud connectivity and credential storage for IoT devices.
- Developing cryptographic device authentication for host applications.
- Configuring platform-specific I2C drivers to comply with SCI2C protocol requirements.
